Five Years Ago Today: Netscape Source Code Released
Sunday March 30th, 2003
On this day in 1998, Netscape made good on its historic announcement to release the Communicator source code. At 10:00am Pacific Time, an early development snapshot of Netscape Communicator 5.0 — which included Navigator and Composer but not Messenger — was posted to mozilla.org, together with a note thanking those who had made it happen. Netscape also published a document describing how the open source development process would work after the code release. Contemporary news coverage came from sites such as CNET News.com, whose article featured quotes from both Netscape and Microsoft, and Wired News, who filed reports both shortly before the release and on the day after.
Take into account that Opera's default UA-string is something like: "Mozilla/4.0 (compatible; MSIE 5.0; Windows XP) Opera 6.05 [en]"
..and many log analyzers / trackers interpret that as MSIE (although it would be easy to identify it as Opera).
In my experience (based on some low/medium-traffic sites), Opera seems to be a bit more popular than Gecko-based browsers at the moment... But Gecko's gaining marketshare relatively fast, which is delighting, of course.
